This is my first post in the forum, after days of following up that thread... I found today Remington Thunderbolt 22LR x 50 rounds at Walmart Van Buren (5200 Van Buren Blvd, Riverside) for $2.17... They put 3 boxes limit per customer, but we were able to buy 6 boxes because my wife was with me.
The had like 50+ boxes

Thanks for the heads up... went down there this morning picked up some Thunderbolt.

Oak Tree in Newhall had .223 (club branded reloads) as well as .22LR as of yesterday afternoon. 49.95 per 100 on the .223 (1 bag of 100 per day per customer).

American Eagle .22LR, 29.95 per 500 (1 500 per customer).

If you are a member they have lower prices as well. Roughly 25.00 per 500 on the .22LR, and 45.99 on the .223.

Don't know how much stock on hand, but seemed to be about 10 bags at a time of .223 on the shelf. Several 500count boxes of the .22LR on the shelf, and they had 50round boxes of the American Eagle .22LR there as well.
